Milk is not a pure substance but rather is a colloid. The protein in it has bunches of peptide bonds but polar ends and would be both hydrophobic and hydrophilic, although the hydrophobic parts tend to curl into the middle of the protein's tertiary structure and hide from the water. The fat component is nonpolar with its solubility depending on how hydrogenated it was. The lactose is a sugar, so it is quite polar.
-- negative polarity -- positive polarity
The polarity is a vector quantity. The resultant of the polarity of bonds determines the polarity of the molecule. In CO2 there is polarity between the two C-O but the polarity is equal and opposite in direction so CO2 doesn't have polarity. If the polarity of bonds is not cancelled then the polarity remains in the molecule.
Polarity
Reversing polarity ,changes the rotation of the device you are changing polarity on.
No. Electromagnetic fields have polarity.
they do not have any electrical property that is polarity sensitive
What can reverse magnetic polarity
Yes integrated circuits have polarity.
a speaker polarity is sub mainframe of the ................................
Its polarity is zero.CCl4 is non polar
the polarity of the battery is reversed
The polarity of both ends of a magnet is different. The positive and negative polarity exist for a magnet.
